Imaging Biological Samples with Optical Microscopy

9.2K
Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.
In optical microscopy, the specimen to be viewed is placed on a glass slide and clipped on the stage...

  • Optical Engineering
  • Embedded Systems

Background:

  • Smartphone-based imaging systems face compatibility challenges due to device variations.
  • Existing solutions often lack flexibility and multi-modal capabilities.
  • Accessible and cost-effective microscopy tools are in high demand.

Purpose of the Study:

  • To develop a versatile and affordable multimodal microscopic imaging system.
  • To address the compatibility and flexibility limitations of smartphone-based microscopes.
  • To provide a cost-effective alternative to laboratory microscopes.

Main Methods:

  • Utilized a Raspberry Pi single-board computer (SBC) as the core platform.
  • Integrated four imaging modalities (bright-field, dark-field, oblique illumination, differential phase contrast) without extra optics.
  • Employed 3D printing and readily available components for construction, costing approximately $122.
  • Enabled remote access and control via Wi-Fi.

Main Results:

  • Achieved an optical resolution of 1.64 μm, comparable to a laboratory microscope with a ×10 objective.
  • Demonstrated successful validation against a research-grade microscope.
  • The system offers four distinct imaging modalities on a single, integrated platform.
  • The developed system is remotely accessible and controllable via Wi-Fi.

Conclusions:

  • The Raspberry Pi-based multimodal microscope offers a flexible, cost-effective, and high-resolution solution.
  • This system overcomes the limitations of smartphone-based imaging, enhancing accessibility.
  • It presents a viable option for various sectors requiring affordable microscopy solutions.
